At equilibrium for reaction 1, in which substrate A is converted to product B, there is 4 times as many molecules of A as there are molecules of B. At equilibrium for reaction 2, in which substrate R is converted into product S, there is 8 times as many molecules of S as there are molecules of R. If these two reactions are coupled, what is the net standard free energy change?
